San Diego woke up to mostly cloudy skies and temperatures hovering around 50 degrees this morning. A wet, windy system is rolling through today, with the heaviest band of rain expected from late morning into the afternoon. Highs should top out near 59 degrees, and there is a slight chance of thunderstorms that could slow the afternoon commute.
Afternoon Winds Pick Up
A Wind Advisory is in effect for coastal and valley areas, with southwest winds around 15 mph and gusts often in the mid-30s. Mountain and desert gusts will be stronger, with values up to 45 to 65 mph in exposed terrain. According to NWS San Diego, secure outdoor furniture and use extra caution if you are driving a high-profile vehicle.
Rain Timing and Commute Impacts
Showers are possible this morning, with steady rain most likely between about 10 AM and 4 PM. New rainfall of roughly a quarter to a half inch is possible near the coast, with locally higher totals in the mountains. Brief heavy downpours and the slight chance of a thunderstorm may lead to ponding on streets and slower travel, so give yourself extra time and watch for standing water. Showers should taper overnight, with conditions clearing from north to south by tomorrow morning.
Beaches and Boaters
A High Surf Advisory is in effect along San Diego County beaches through tomorrow, with 4 to 6 foot surf, sets as high as 8 feet, and dangerous rip currents likely. Local reporting has highlighted the risk of beach erosion and hazardous swimming conditions; see the Times of San Diego for more on coastal impacts. Boaters should avoid exposed waters while advisories remain in effect.
Mountains and Travel
Snow will begin to accumulate above roughly 4,500 feet, with 1 to 6 inches expected up to 7,000 feet and 8 to 12 inches on the highest peaks. A Winter Storm Warning covers mountain zones through tomorrow morning. Travel into the mountains this afternoon and evening could become hazardous; if you must go, carry chains, slow down, and check road reports. In lowland areas, patchy fog and frost are possible late tonight into Friday where skies clear.
Practical Tips
Plan for a slower drive, secure any loose outdoor items, and stay away from the ocean while advisories are in effect. For the latest watches and warnings, check the National Weather Service and local transportation agencies before heading out.
